FAQ
Why are parts of the M0519 pins unable to control the output to a high or low state after being configured as the GPIO function? Issue Date：2018-11-26
Since the pins with EPWM0, EPWM1, and BPWM output functions (P0.0 - P0.5, P1.0 - P1.5, P5.6 - P5.7) are often used to control the upper and lower MOSFET of bridge circuit. To avoid MOSFET damage caused by simultaneous high output at power-on, the initial state of these pins is determined by Config0[12:8].
The user can change the settings of Config0[12:8] such that these pins are controlled by the GPIO register after power-on. Or PWMPOEN[4:0] is set to 0 to release the Hi-Z state after power-on when the program starts to operate.
